SUPPORT FOROONDUCTORS.

Application filed March 21, 1922. Serial No. 545,555.

T 0 all 10 ham it may concern Be it known that we, MERRILL W. MANZ andSAMUEL S. MATTHES, citizens of the United States of America, residing atMansfield, in the county of Richland and State of Ohio, have inventedcertain new and useful Improvements in a Support for Conductors, ofwhich the following is a specification.

Our invention relates to a support for conductors and relates moreparticularly to the supporting of trolley wires from catenary ormessenger cables.

Our invention has for its object the supporting of trolley wires frommessenger cables and maintaining the trolley wires and messenger wiresin a predetermined spaced relation and resides in the construction, combination and relation of the various parts more fully set forth anddescribed herein.

In the drawings accompanying the specification- 1 Fig. 1 is a view inelevation looking 'in a longitudinal direction with respect to thetrolley wires.

Fig. 2 shows a side view in elevation of Fig. 1.

Fig. 3 is a schematic view looking down upon a pair of catenary cablesbelow which are the trolley wires supported by three of my devicesindicated at S, S and S".

Fig. 4 is a schematic drawing showing more clearly the method in whichthe device 5 of Fig. 3 is used.

Fig. 5 is a top view of the trolley clamping member taken on the line5-45 of Fig. 1.

Fig. 6 is an end view of Fig. 5 looking in the direction indicated bythe arrow Y or of the clamping element in Fig. 1 looking in thedirection Y.

While our device is particularly adapted to the supporting of thetrolley ,conductors from catenary cables at a point where one trolleywire diverges from another as shown in Fig. 3, still it is not confinedto such a lirn ited purpose, but can be made use of in va riousconstructions in combinations of overhead catenary cables and trolleyconductors, as for instance, it maybe desired-to support two paralleltrolley wires for manymiles suspended from their individual catenarycables and maintained a predetermined distance apart.

Inour preferred construction we employ the vertical eme t re whichsensed the trolley conductor directly from the messenger cable, thediagonally disposed elements BB for maintaining one of the trolleyconductors in a fixed relation to the messenger cable of thevoppositeconductor and 'the element C for maintaining the trolley .conductors ina definitely spaced relation.

The elements AA each comprise the sup,- porting rod 1 to the upper endof which is secured a two part clamp comprising the clamping members22provided with socket means 3 to engage the enlarged head 4 of themember 1 and also provided with a recess5 to receive and grip a.catenary cable. I

The clamping members2-2 are held in a clamped position upon themessenger cable and the rod 1 by means of the clamping bolt and nut 6.The projecting-end of the bolt adjacent the nut is split at 7 so thatthe end ing a slot 12 in one end of the bolt for looking the nut inplace as already described. The member 8 at its upper end is providedwith a socket13 having, as shown, a threaded recess 14: to receive thethreadedend of the supporting and 1. The clamping member 8 is alsoprovided with a pair of spaced transverselyprojecting lugs 15 having arecess to receive a clamping bolt andrnut 16 likewise provided with aslot 17 whereby the bolt and nut are locked together.

The diagonal bracing and I supporting elements B-B each comprise "themember 18 to the upper end ofwhich is attachedclamping means as shownsecured to the upperend ofthe supporting rod 1. and constructed inlike,.manner as shown and indicated bythe numerals. The members B--B areofii'set asshown in. Fig. 2 in order toallowthe clamping members thereonto rest, alongside the clamping members on. the supporting rods 1:-1 andto gripthe messenger, cable. I

.TQ-the loweren'd of each' rod'18l8 is secured a socket. member 19having, oneend internally threaded to receive ,th'efithreaded" end oftherod 18 d h liowermendvofgthe fiock-et i Provider], w thsto bepositioned between the lugs l515 and held iii pivota'l position by meansof the bolt and nut 16. Y

Under normally installed conditions the axes of the elements B Bcoincide with the dotted lines X-X, but in order to Show the details ofconstruction the elements B-B are shown as moved out of normal positionabout their pivotal point 16.

The element C comprises the spreader member 21120 each e of wh ch s seur d a Socket memb r 22 pro id d a Qn nd it a threaded recess to receivethethreaded end f th r rl '2 r. m1 a so Pr v ded with a ug to be .pqsitned between th l g l l he d. in pivotal pos iqn y the b l an installingour invention the clamping "supper end ,of'the elements rs at secured. ft1 e m Ss' IisQ ,c bl fl M ly and the clampi g members at t e? upper side f t leme ts f}? are .I Cabl s ML-M respe ti y along si e 0 ileclamps n t member ALTA, The trolley conductors are then e ured ba a as1' W v8 and 9- Thi qn truetion gi, es a igid, si p and lfcon ain leri sfQr sup rt ng the t l y Wi s om their ind fili l e l a 'y ab i ma ntaned ,sr) 1 e at en- C mb ai ns Qf'a mila fiure hav be n ma e Where he rai -i m mb s A, B me G 1 net e n? catc e lev .06 u in r fang nf We have S9, $.tif $lth lower clam] member 8 a to b a to SQQUIQ ale-sq one as o anoi th od 1, 1.8 and 21 and in dj tabl rela on the 'ei T s a a r ry smple rr nge ent wh c e 1 QbY Q'us ad anta s ver a s mi a an sm W ere theva u pa t a no united in unitary .wns r mt n- The e as bv us y many vara on which can be n'rade in the construction and arrangement oftheinvention herein, insed and h wnf h ch w ll suggest heme ies t 'th s'e klled he an therefore, e do not wish to, be limited other thanby ourclaims.
